As stated in the title, updated the drivers (booted in W10 safe mode and used DDU) to 17.12.2. I have noticed that after exiting graphics-heavy loads like games or benchmarks (like Unigine Heaven or Furmark) that now the GPU is stuck at max clock speeds for core (stock clock speeds with 1070mV undervolt and HBM at its max of 850 MHz overclocked (max my Vega 56 will clock HBM at without crashing in games)), max voltages for both of them and it's running at around 75 degrees C making the fan stuck at an audible RPM trying to cool the core and HBM. This did not happen with the previous driver I had installed, which was 17.11.1, or any other past drivers for that matter.
